Thermo Scientific™ NHS-Phosphine

Thermo Scientific NHS-Phosphine is an amine-reactive compound that can be used to derivatize primary amines of proteins or amine-coated polymer surfaces for ligation to azide-tagged molecules.


  • Soluble—reagent easily dissolves in water-miscible solvents for subsequent dilution in aqueous reaction mixtures with cell lysates and other biological samples
  • Compatible—reaction chemistry occurs effectively in simple buffer conditions; requires no accessory reagents such as copper or reducing agents
  • Specific—NHS esters are specific for covalent attachment to primary amines (side chain of lysine or N-terminus of polypeptides)
  • Chemoselective—azide and phosphine groups do not react or interfere with components of biological samples (bioorthogonal) but conjugate to one another with high efficiency
